Secondary-structure prediction of the PL motif-1. The table shows the consensus sequence obtained from the alignment of the peach PL sequences, the 5 PLs of the Ma protein and the WW-domain consensus sequence obtained from Vitis vinifera sequences. H signifies a helix residue. Predicted stands for extended beta sheet (E) are surrounded by the tryptophans (in blue). (DOCX 17Â kb
